REXROTH柱塞泵
柱塞泵等泵類在造船、石油開采、載重機等方面廣泛應用。2008年船舶產量達到15000噸,載重噸數量占世界市場的21%,到2015年將成為世界*造船大國。為了保證船的正常航行或系泊,滿足船員和旅客的生活需要,每條船都要配有一定數量的、能起相應作用的船用采,船用泵是重要的輔機之一。據不*統(tǒng)計,在各種船舶輔助機械設備中,各種類型和不同用途的船用泵的總數量,約占船舶機械設備總量的20%-30%,船用泵的價格在船舶設備費用中所占的比重也比較大。在總的造價中,船用泵約占全船設備費用的4%-8%,一般情況下.一條中型以上船舶的船用泵采購可達1000萬元以上。
REXROTH柱塞泵是往復泵的一種,屬于體積泵,其柱塞靠泵軸的偏心轉動驅動,往復運動,其吸入和排出閥都是單向閥。當柱塞外拉時,工作室內壓力降低,出口閥關閉,低于進口壓力時,進口閥打開,液體進入;柱塞內推時,工作室壓力升高,進口閥關閉,高于出口壓力時,出口閥打開,液體排出。 帶滑靴結構的軸向柱塞泵是目前使用zui廣泛的軸向柱塞泵,安放在缸體中的柱塞通過滑靴與斜盤相接觸,當傳動軸帶動缸體旋轉時,斜盤將柱塞從缸體中拉出或推回,完成吸排油過程。柱塞與缸孔組成的工作容腔中的油液通過配油盤分別與泵的吸、排油腔相通。變量機構用來改變斜盤的傾角,通過調節(jié)斜盤的傾角可改變泵的排量。現(xiàn)貨庫存力士樂柱塞泵德國博世Rexroth廠家*!
